Best months by climate

Start well
Plant snapdragon with confidence
Plant seedlings. Prepare the final position first, retain the existing root-ball level and water thoroughly after planting.
- Sowing or planting depth
- Plant at the existing crown or root-ball level unless the label specifies otherwise.
- Germination or establishment
- Not normally started from seed in this guide; establishment speed depends on plant size, season and root condition.
- Spacing
- Use the mature width on the label; Patch's broad family guide is only a starting point.
- Soil
- Well-prepared soil with compost and reliable drainage; usually ph 6.0–7.0.
Feeding
Support steady growth
Use compost before planting and a flower-forming feed only when the species benefits from it.
Water
Keep moisture balanced
Keep moist while establishing, then water deeply when the surface dries.
Maintenance
What to do as it grows
Remove spent flowers where appropriate and maintain airflow around new growth.
Harvest or display
Know when it is ready
Flowers in 10–14 weeks. Readiness varies with variety and weather; use colour, firmness, size and the supplier's maturity notes rather than the calendar alone.
Problems and companions
Keep your patch healthy
Common watch-outs
Aphids, thrips, snails, powdery mildew and grey mould can appear in crowded or damp growth.
Useful neighbours
Combine plants with matching water and sunlight needs, and stagger flowering times for a longer display.
People and pets
Safety note
No Patch-specific toxicity warning is recorded. That does not prove the plant is safe—check the exact species with a veterinarian or poisons service if children or pets may eat it.
Moving plants
Biosecurity note
Check local weed, invasive-plant and interstate quarantine rules before sharing or moving unfamiliar plant material.
Transparent guidance
How to use this guide
Patch gives a broad Australian starting point, not a guarantee for every variety or garden. Read the Patch methodology and sources, check the latest Bureau of Meteorology climate information, and confirm interstate restrictions through Australian Interstate Quarantine.
